The kindergarten's summer vacation starts tomorrow! Sakura suggests they take a trip to her hometown with Hiiragi, Koume, and Tsuchida-sensei. Tsuchida-sensei gets excited when Yamamoto-sensei decides to join them, and the six of them make plans to visit the hometown of Sakura and Tsuchida-sensei.
Satsuki is delighted her brother is finally visiting home, but when he spends all of his time looking after the girls and staring at Yamamoto-sensei, her mood turns sour. The situation comes to a head when Tsuchida-sensei does not even realize his sister prepared dinner. The group heads to a nearby shrine for a summer festival, but Satsuki's feelings are still unresolved.
I wish my brother would be like that, too T^T He doesn't like me going around with him. And I'd like to go to one of those Festivals! And try on a yukata~
